Pulse abnormality detecting device

Abstract

A pulse abnormality detecting device comprises a band attached to a wrist, a first sliding member with which the band is armored and which slides in the circumference direction of the band along the band, a second sliding member which is slidably provided on the first sliding member and which slides in the axis direction of the band, a pulse sensor which is provided on the second sliding member and which is provided in such a manner that the position of the sensor can be adjusted to the inner side or the side of the band, and a pulse abnormality detecting unit for detecting the abnormality of the pulse from the output data of the pulse sensor. The device can accurately detect the pulse of a user with high precision, adapting to a personal difference.

Description

TECHNICAL FIELD[0001]The present invention relates to pulse abnormality detection apparatuses for detecting pulse abnormalities of users.BACKGROUND ART[0002]Examples of pulse abnormality detection apparatuses for detecting pulse abnormalities of users include a medical watch disclosed in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 5-52975). In the medical watch, a pulse sensor is fixed at a given position inwardly of a wristwatch band so as to be brought into intimate contact with a position at which a pulsation of a wrist wearing the medical watch is detectable, a temperature sensor for detecting a body temperature is fixed at a given position inwardly of the wristwatch band, and outputs of these sensors are supplied to a controller. The controller compares an output waveform from the pulse sensor with a standard waveform, stored in advance, to perform blinking display on a display module and / or issue an alarm when the comparison result falls outside a...

Benefits of technology

[0004]The present invention has been proposed in view of the above-described problems, and its object is to provide a pulse abnormality detection apparatus capable of accurately detecting a user's pulse with high precision while adapting to individual differences.

[0021]Moreover, the main body of the band is provided with the pulse abnormality detector; thus, a pulse abnormality can be recognized by the main body of the band, and the user wearing the band, for example, can recognize a pulse abnormality on the spot.

Problems solved by technology

Specifically, since a wrist has two large arteries such as a radial artery and an ulnar artery, pulses of both of radial and ulnar arteries are detected if the pulse sensor is merely placed at a position at which a pulsation of the wrist is simply detectable, and frequency change and / or phase change are / is caused in detected pulses, thus making it difficult to accurately detect pulses.
